1VIA/Wondermedia VT8500/WM8xxx series SoC PWM controller 2 3Required properties: 4- compatible: should be "via,vt8500-pwm" 5- reg: physical base address and length of the controller's registers 6- #pwm-cells: should be 2. The first cell specifies the per-chip index 7 of the PWM to use and the second cell is the period in nanoseconds. 8- clocks: phandle to the PWM source clock 9 10Example: 11 12pwm1: pwm@d8220000 { 13 #pwm-cells = <2>; 14 compatible = "via,vt8500-pwm"; 15 reg = <0xd8220000 0x1000>; 16 clocks = <&clkpwm>; 17}; 18
